H-O or O-H?

[Plane]

when Wolf Blitzer asked about the possibility of a "dream ticket" featuring the two of them, the question drew extended applause from the celebrity-filled crowd - and prompted a funny response from Obama who told Blitzer there was "obviously a big difference" between an Obama/Clinton ticket and a Clinton/Obama ticket. Tellingly, neither candidate rejected the notion. Indeed, after Obama gave an extended riff on what he'd look for in a running mate and members of his cabinet, adding that Hillary would make anybody's short-list, Clinton said, "I have to agree with everything Barack just said." Was this a preview of a night this summer in Denver, minus the falling balloons?
